Jensen Ackles has confirmed that Lisa and Ben will return on Supernatural.

Speaking to TV Line, Ackles explained that his character Dean will struggle with his feelings for them.

"They will be back," he said. "I can't say necessarily how, but that story will be explored and it will be explored heavily."

Ackles continued: "I think there's a part of [Dean] that was left with them. But I think he knows deep down that it would never work. And I think that's going to be a very emotional situation that he's going to have to deal with."
